(FR) ROUE DE VEHICULE FERROVIAIRE ET PROCEDE DE FABRICATION CORRESPONDANT
Abstract
(EN) The wheel has a central axis (Α-Α') of rotation and comprises a rim (4) having two coaxial crowns (10), a tyre (6) surrounding the rim (4) and comprising a bearing portion (22) engaged between the two crowns (10), and two resilient rings (8), each resilient ring (8) being interposed axially between the bearing portion (22) and a respective crown (10). The wheel comprises at least one set of centring ports (26), each set of centring ports (26) comprising a plurality of centring ports aligned along an alignment axis (Β-Β') parallel to the central axis (A-A'), each set of centring ports (26) including at least one centring port (10A) provided in a crown (10), at least one centring port (8A) provided in a resilient ring (8), and a centring port (22A) provided in the bearing portion (22).
(FR) La roue présente un axe central (Α-Α') de rotation et comprend une jante (4) possédant deux couronnes (10) coaxiales, un bandage (6) entourant la jante (4) et comprenant une partie d'appui (22) engagée entre les deux couronnes (10), et deux anneaux élastiques (8), chaque anneau élastique (8) étant interposé axialement entre la partie d'appui (22) et une couronne (10) respective. La roue comprend au moins un jeu d'orifices de centrage (26), chaque jeu d'orifices de centrage (26) comprenant plusieurs orifices de centrage alignés suivant un axe d'alignement (Β-Β') parallèle à l'axe central (A-A'), chaque jeu d'orifices de centrage (26) incluant au moins un orifice de centrage (10A) ménagé dans une couronne (10), au moins un orifice de centrage (8A) ménagé dans un anneau élastique (8), et un orifice de centrage (22A) ménagé dans la partie d'appui (22).
